SSRF Vulnerability in BentoML Python Library Exposes Systems to Remote Attacks

CVE-2025-54381

What is CVE-2025-54381?

CVE-2025-54381 is a significant vulnerability found in the BentoML Python library, widely used for developing online serving systems optimized for artificial intelligence applications and model inference. This particular vulnerability, present in versions 1.4.0 to 1.4.19, is characterized by a server-side request forgery (SSRF) flaw. It allows unauthorized remote attackers to manipulate the server into making arbitrary HTTP requests. The issue arises from how the library handles file uploads via multipart form data and JSON request processing. Specifically, it fails to validate the user-provided URLs before downloading files, exposing the system to potential exploitation. This design, which is promoted in the documentation, creates an inherent risk where deployed services become vulnerable by default, enabling attackers to target sensitive resources and internal network addresses. A patch addressing this vulnerability was introduced in version 1.4.19.

Potential impact of CVE-2025-54381

1. Unauthorized Access to Internal Resources: Exploiting this vulnerability can allow attackers to send requests to sensitive internal services, leading to unauthorized access and information leakage from protected interfaces that should not be exposed to external networks.

2. Arbitrary Code Execution: If the attacker can manipulate the request sufficiently, they could leverage the SSRF to execute commands on the server's operating system, potentially leading to full system compromise and control over deployed models and AI applications.

3. Data Breaches and Financial Losses: The exploitation of this vulnerability could result in data breaches where confidential information is accessed or exfiltrated. Organizations may face significant financial repercussions, including regulatory fines, loss of customer trust, and costs associated with incident response and remediation efforts.
